Testing Using Mac OS X

Click on System Preferences >> Phidgets (under Other) to activate the Preference Pane

Make sure your device is properly attached

Double click on your device's objects in the listing to open them. The Preference Pane and examples will function very similarly to the ones described above in the Windows section.

Testing Using Linux

For a general step-by-step guide on getting Phidgets running on Linux, see the Linux page.

Using a Remote OS

We recommend testing your Phidget on a desktop OS before moving on to remote OS. Once you've tested your Phidget, you can go to the PhidgetSBC, or iOS pages to learn how to proceed.

Technical Details

General

Produces a voltage over -10V to +10V. This voltage will be asserted up to +-20mA (short-circuit). An error will be reported when this current is exceeded, and the voltage the customer is getting is no longer accurate. The voltage is produced with 12 bit resolution (4.8mV). The update rate or frequency of the outputs is dependant on the speed of your system.

Connections

The terminal blocks on this board are labelled on the underside to save space:

Isolation

The 1002 is not isolated. All 4 channels use the same ground.

Current

The PhidgetAnalog board will limit the available current per channel at approximately 20mA. For reliable results, don’t approach this limit, as it will vary from channel to channel. For maximum accuracy, limit the current to 5mA. If more than +- 20mA of current is drawn, the device goes into a constant current supply mode. When this happens, the current will be held constant at it’s maximum value, and the output voltage will depend on the value of the load that the device is trying to drive.

If your application requires a larger current source / sink, the analog output can be used as an input to a larger external amplifier circuit.
